Pretty good. You have a few typos ("in empty spaceon", "what Emperor Palpatine would have done the Admiral") and a few places where commas are needed ("Darth Vader asked COMMA without turning. “I don’t know COMMA Lord Vader,” ), but the prose is well done. You are short on description, which draws attention to the characters--well to Vader, really, as the officer remains faceless. Vader's thoughts near the end of the story, which was an explanation I looked forward to, were accuratly ruthless and subserviant--and somewhat poignant because of your main point,that being how this will be the first of the famous choking-officers scenes (and of the "emperor is not forgiving" though/dialogue, apparently). Nice pace--almost calm. A pretty nice vignette piece.

Intriguing little oneshot. I think I might have expected a little more ambiguity in Vader about his actions...but this was still pretty good. Nice idea.
